Additional information you deem important

It is happened due to removal of domain login and the polici

At present in spicedb we have userid prefixed with domain
Example : 0c883527-8316-4711-b7e9-ded734bf96ed_84319f2a-046a-44d7-b24c-06b15d38ac74
Here 0c883527-8316-4711-b7e9-ded734bf96ed is domain ID,
we should store without domain id prefix.

We should remove the EncodeDomainUserID at

supermq/internal/api/auth.go

Line 46 in e8e17f5

resp.DomainUserID = auth.EncodeDomainUserID(domain, resp.UserID)

And then remove DomainUserID from authn.Session
at

supermq/pkg/authn/authn.go

Line 33 in e8e17f5

DomainUserID string

Then we need to perform all authorization with UserID

This creates another problem of listing domain specific entities directly from spicedb

The proposed solution is doable only after implementing clients and channels listing without depending on SpiceDB #2606 #2605
